Application filed November 28, 1913, Serial 110.- soe,43e.'

T 0 all whom it may concern:

Be it known that I, SAMUEL CRUMP, a citizen of the United States, and a resident of New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Machines for the Manufacture of Printers Rollers, of which the following is a specification. I e

The invention pertains more -pa'rt1cularly to means for applying in a uniform and efficient manner a coating of glue-glycerin or other sultable composltion upon the exterlor surface of a prmters roller, e1ther 1n the originalmanufacture of the roller or in having the roller of uniformdiameter and surface and to afford means for coating a roller and leave it of uniform diameter and surface is the object of the present invention, which, in use, has proved to, be both efficient and successful.

In accordancewith my invention I mount I the printers roller between two spindles of lathe character and cause the same to rotate roller the melted composition, the said material being carried by a specially constructed receptacle which is caused to travel along I the line of the roller with' its open side in close relation thereto so as to'apply the material to the roller or permit the roller during its rotation to take the material therefrom. The receptacle carrying the material for the coating is mounted on a frame'whi ch I will preferably be operated to travel from a; screw and carry a kettle orother container having a discharge leading to the receptacle which feeds the coating solution to the roller, so that said receptacle may always remain in substantially filled condition.

The invention will be fully understood from the detailed description hereinafter presented, referencebeing had to the accompanying drawings, in which;

Specification of Letters Patent Figure '1 is a perspective view, partly broken away, of a machine embodying my invention and shown as in the operation of applying a. coating to a printers roller Fig.

tion of the "receptacle detached from the machine; Fig. 4 is a detached View, partly broken away, of said receptacle, said View being the reverse of that shown inFig. 3

and representing the receptacle as having its rearside turned around to the front,

and Fig. 5 is a top-view of a portion of the receptacle and its support; .7

In the drawings 10 designates a suitable bed-plate ortable mounted upon legs 11 and provided atlits opposite ends with'stand'ards 12 having bearings 13 for spindles or shafts 14 of customary character in lathe work and therefore requiring no special description.

One of the spindles 14, commonly known as the live spindle, has mounted on it a drive-wheel 15 and gear wheel l6,'the latter being in mesh with a gear-wheel 17 secured upon the end of a horizontal screw 18 extending from one end to the other of the a drip-pan 20 which is somewhat. greater than the length of the-printers rollers to be coated with the use of the machine. Upon the screw 18 is mounted a frame 21 having a i post 22 adjustably secured thereto, said frame 21 having'an undercut groove 23 in and during such rotation I apply to the its upper surface to receive the lower end of said post in a manner customary in lathe The receptacle 24 is open at its rear side, as

shown in Fig.2, and comprises a bottofn 25, a front' end 26, and corresponding sides '27, the latter converging downwardly tothe bottom 25 and extending upwardly and of the principal features of -myinvention. .1075 i frontwardly beyond the front end 26, as

clearly shown in Figs. 2 and 3. The rear edges of the sides 27 of the receptacle are concaved in their lower portions, as shown in Fig. 2, and the bottom 25 of the receptacle is formed with a frontwardly extending section 28 by means of which the receptacle maybe secured to a supporting plate 29, said plate being extended at one end and adapted to be detachably secured to the post 22. The extension 28 of the bottom of the receptacle is formed just in front of the front end 26 with a hole 30, and the plate 29 is below said hole cut out, as at 31. The front end 26 of the receptacle inclines clownwardly and rearwardly and its upper edge is over the hole 30, and the frontwardly extending portions of the sides 27 converge downwardly to said hole 30 and the purpose of the hole is to permit any overflow of the solution from the receptacle to pass downwardly through the hole 30 and cut away portion 31 in the plate 29 and fall into the drip pan 20. It is my-purpose that the receptacle 21 shall, when in use, receive a substantially constant feed of the solution from the container or kettle 32 and that the overflow from said receptacle shall be directed to and permitted to escape through the hole 30. I shall preferably secure upon the plate 29 one or more metal blades or wings 33, which will correspond exactly with the adjacent side of the receptacle 21,

being inclined and concaved at their rear lower edges correspondinglywith the said side. The frame 21 not only supports the plate 29 and receptacle 21, but has secured to it a crane or arm 31-from which the bucket or container 32 is suspended, it being the purpose that the bucket or container 32 shall travel with the frame 21 and 'receptacle 21 and have a substantially constant discharge through its outlet 35 into said receptacle.

. spindles 11 and rotatable.

I illustrate a printers"roller 36 on the machine, said roller being held between the The roller 36 shown comprises a stock 37, a body 38 which may be of sponge rubber, a skin of linen or the like 39 tightly inclosing said body and an outer coating 10, the application of said coating to the roller being the purpose of the present invention. The interior and body of the roller 36 may be of any suitable character, since the invention comprises a machine for applying a .coating to a printers roller regardless of the character of the body-portion of the same. 1 illustrate one construction of printers roller, but will apply the coating 10 with the use of my invention on printers rollers generally whether new rollersin the course 7 of construction or old or damaged rollers requiring resurfacing.

In the employment of the machine of my invention the frame 21 carrying the receptacle 21 and container 32 will be moved to the right hand portion of the table or bedplate 10, and the roller 36 to be treated will be secured between the spindles 11, and thereupon, after the adjustment of the receptacle 21 to said roller, the discharge from the bucket or container 32 will be opened to permit the flow ofthe coating-composition into the said receptacle, filling such receptacle to the top of the front end 26 thereof, and power willthen be applied to the wheel 15 for the purpose of rbtating the printers roller and through the gear wheels 16, 17 the screw-shaft 18, the result being that during the rotation of the roller 36 the frame 21 will be caused to travel along the roller and toward, in the construction illustrated, the left hand end thereof. The receptacle 21 will be adjusted rather close against the body of the roller to be coated, so that during the travel of said receptacle said body may receive therefrom a thin coating of the solution-composition. After the receptacle 21 has traveled toward the left the full length of the roller 36, it will be returned to the right hand end of the roller and readjusted "against the same and then caused to travel toward the left, leaving another thin coating of the composition material on the roller. This will be repeated as often as may be required for obtaining a coating 10 of the desired or requisite thickness. The composition-material in the bucket or container 32 is kept hot, and hence the composition is kept liquefied and in a condition to flow, into and overflow the receptacle 21. The overflow from the receptacle 21 passes to the drip-Ran 20 as hereinbefore described. The sides 27 of the receptacle, owing to their inclination and being cut at their rear edges to partly fit the body of the roller, are important, in that the coating by reason of said construction becomes evenly 11o applied to the roller: and, without streaking or leaving a spiral line on the roller. The relative proportions and formation of the front end 26 and sides 27 of the receptacle 21 are also importantin that all overflow is kept under control and directed to the discharge opening 30, whence th overflow passes to the drip-pan 20. The presence of the blades or wings 33 to engage the surface of the roller as a trail after the receptacle 21, is important in that they aid in the production of a smooth uniform .coating on the roller and without streaking so that at all times. the roller 36 may throughout its length receive asubstantially uniform layer of the material from said receptacle.

I have hereinbefore described the invention as employed for applying a coating to a printers 'roller whether said roller was in the course of manufacture or an old roller requiring to be resurfaced It is to be understood, however, that my invention is not limited to merely applying the exterior coating on a printers roller, but may be employed for forming the entire roller of printers roller, or other suitable composition, and

in that use of theinvention the stock for the roller would be applied to the machine described and the receptacle carrying the -melted composition caused to travel along the same a suflicient number of times to create a printers roller of the requisite diameter.
